To all whom it may concern:

Be it known that I, HENRY P. Ham errors, a citizen of the United States, residing at Maroa, in the county of Macon and State of Illinois, have invented a certain new and useful Improvement in Grain- Handling Devices, of which the following is a specification.

This invention relates to grain handlingdevices, and has for its object to provide a new and improved apparatus of this description. Y

The invention is illustrated in the accompanying drawings, wherein- Figure 1 's a side elevation of the elevating apparatus; Fig. 2' is an end view of the elevating apparatus showing the vehicle from which the grain is discharged and the apparatus for controlling it; Fig. 3 is a plan view of the horizontal portion of the elevating apparatus; Fig. 4 is a sectional view of a portion thereof at the point where the two sections join; Fig. 5 is a sectional view taken on line 5-5 of Fig. 3; Fig. 6 is a sectional view taken on line '6() of Fig. 1; Fig. 7 is a view of the vehiclecontrolling apparatus; Fig. 8 is an end view of the vehicle-controlling device shown in Fig. 7; Fig. 9 is a sectional view taken on line 9-9 of Fig. 8; Fig. 10 is a view of the sprocket wheel shown in Fig. 9; Fig. 11 is a top view of the device shown in Fig. 7.

Like letters refer to like parts throughout the several figures.

The device is adapted to be used for unloading and elevating corn or other grain or material, and delivering it to a desired p oint. The elevating device as illustrated in ig. 1 is made up of a plurality of sections 1, 2 and 3 which are hinged together in some suitable manner, there'being a continuous vatin conveyer 4 running along all of these sections. The sections 1 and 2 when the device is in operation are preferably in an inclined position, while the section 3 is arranged in a substantially horizontal position. The elevating device as herein shown is mounted upon a truck 5 so that it may be readily moved from place to place. livotally connected to the truck is a support 6. The eledevice is suspended from this support in any desired manner, as by means of the rope 7 which is fastened to the support (see Fig. 2), and which passes around; a pulley 8 attached to a bracket 9 on the ele- 'vating device, and thence around a pulley 10 connected with the support. and thence to a Windlass (58 and cleat or the like 11 on the truck. By means of this rope the elevating device can be lowered onto the truck. or raised to the position shown in Fig. 1. The device is connected to the truck by means of the pieces 12 hinged to the parts 13 on the truck. Sections 1 and 2 of the elevating device are hinged together by the triangular hinged parts 14 which are fastened together by bolts 15, 16. \Vhen it is desired to fold the parts, the bolts 16 are removed and the section 1 folded upon the section 2. l'linged-braccs 17 connect the support 6 with the truck. This support forms what may be called a folding derrick. 1

The material is discharged into section 3 of the elevating device, and is there taken up by the continuous conveyor. This section 3 is at an angle to the remainder of the elevating device. An arrangement is provided for permitting the movement of the continuous conveyor in all the various po sitions of the section b. This section is hinged to the other partof the elevating device at 18 so that it can be folded up when the device is not in use. The upper part of the continuous conveyor passcs along the floor 15), the grain or other material being moved along this iioor by the flights 20. At the end of section 2 the chain of the conveyor passes beneath the driving sprocket 9.1 above the guiding wheels 22, 23. The whccls 22 and 23 act as guides. There is also a guiding device 24 for the upper part of the conveyor.

The various wheels or guides may be supported in any desired manner, and as herein shown are supported upon the brackets 25, one on each side of the elevating device. The section 3 is provided on the interior with an inclined receiving face 26 at one. side. and a chute 27 at the other side. The

'inclined receiving face covers a part of the conveyor and prevents too much material from being discharged thereon. TlllS may be termed a limiting device for limiting the feed to the conveyor. Associated with the section 2 are the movable side bOilIdS 28 which may be moved out of the way as shown in dotted lines in Fig. 1 when it. is desired to fold the sections of the elevating device. The section 3 is preferably provided with a supporting leg 29. The driving sprocket 21 may be actuated in any desired manner, as, for example, by the driving shaft 30 driven from an suitable Source of power.- It will be un erstood, of course, that there are two of these driving sprockets, one on each side of the device.

The material is dumped into the section so as to be acted upon by the conveyer. As shown in Fig. 2 a vehicle 31 is shown in position ready to discharge grain into secvided for automatically 'discharging this grain As herein shown means is provided or lifting the front end of the vehielelso that the material will slide out at the rear end. A; frame 32 is arranged in lprop'er' position with relation tothe vehicle, said frame being provided'with a flexible lifting device 33 which'is passed over the hub of the front wheels (see Fig. 2), and between the bed and folly of the wheel, there being means provided for operating the flexible lifting device so as to lift the vehicle to the proper position. As herein illustrated there are two flexible lifting devices 33 which pass over pulleys at the top of the frame 32, one going to each wheel. These flexible lifting devices arevconnccted at 60 to a belt or chain 61. Connected with this chain-at 62 is a. detachable chain or belt 63 which engages a sprocket wheel 64, and is connected to' the end of the chain 61. The chain 61 engages a wheel or pulley 5 which may in this instance be a plain wheel. The spocket wheel 64 is connected with a gear wheel35. lVhen this construction is used the chaintil need only be a plain chain as the driving is done by the detachable belt 63 which is arranged to engage the teeth on thedrivin sprocket M. A socket wheel 36'is mountet in"proximity to the gear 35, and is provided with engaging projections 37 which engage the teeth of the gear as s rocket wheel 36 is rotated so as to rotate t e goal; and wind the flexible lifting devices. The sprocket wheel 36 is driven in any desired manner, as by means of the belt 38, sprocket wheel 39 and shaft 30. Some means is rovided for connecting and disconnecting the sprocket wheel 36 from the drivin shaft. The arm 43 has a part in the pat of an engaging part 45 on the detachable chain so that when the detachable chain has been moved to lift the front end of the wa on the proper amount the part 45 will strike the arm 43 so as to throw the parts out of gear and stop the further upward movement of the wagon. Some suitable means is provided for controlling the return movement of the wagon. As herein shown a frictional braking element 46 is feathered to the shaft 47 of the gear 35. A cotiperating frictional element 48 is fastened to the frame 49. Some means is provided for moving the two elements rela tivcly to bring them into frictional contact. As shown in Fig. 9 a controlling rotate and may yet be movedlongitudinally 3 along the shaft. By moving this handle it will be seen that the shaft 47 and gear '35 and sprocket wheel 64 may be controlledtoleither hold thewagon in any desired position, or lowerit slowly. It will be seen lth-at fwhen the sprocket wheel 64 is rotated 7. 1clock-wise the detachable'chain 63 moves [downwardly pulling with it the up per art pulling upon t e 8X1 o'f'thechain 61, thus so as to lift the veble lifting device 33 hicle..

The use and o eration of my invention are as follows: VBhen the elevating device has been moved to the desired position by means of the truck 5 the sections of such elevating device are unfolded and the device is raised by mcans of the folding derrick, rope 7 and Windlass 68 to the position shown in full lines in Fig. 1. The lifting device or jack for the front end of the vehicle or wagon is then placed in proper position and the vehicle moved into proper relation with the section 3 of the elevating device. The continuous conveyer isthenset in motion. The clutch member 40 is then moved by means of the controlling device 42 to en age the sprocket wheel 39. This rotates tiegears 36 and 35 and the sprocket wheel 64, and Winds up the flOXl- 'ble lifting devices which are connected to the hubs of the front wheels of the vehicle. The vehicle is then inclined so that the material therein will slide out into section 3 of the elevating device where it is engaged by the flights and moved upwardlyto the point of delivery. The receiving face 28 receives the superfluous material and prevents the elevating device from b81115; clogged. \Vhen the part 45 cngagcs thc arm 43 the clutch member 40 is move: throw the parts out of gear and stop further upward movement. At this the handle 50 is moved so as to bring the clutch members 46 and 48 into frictional contact so that the lowering of the front end of the vehicle may be properly con trolled.

It will be seen that there is here provided a port-able elevator and grain dum which may be easily and quickly place in its operative position, and which will cheaply and efficiently handle the grain or other material in connection with which it is used. The single continuous conveyor has a part in each of the sections of the elevating device, and the arrangement is suchthat this conveyer will work when section 3 is in any of its various positions.
